Grid references locate places on the map. They consist of one (Ireland) or two (Great Britain) letters followed by an even number of digits. The letters define a (100x100)km^2 square (a 'myriad' in Geograph-speak) and are best looked up on an overview map. The numbers locate the position within that square. To find a location, split the block of numbers in two. The first block is the easting, i.e. the distance from the western edge of the myriad. The second is the northing - the distance from its southern edge.

Grid references always specify square areas, not points. The more digits there are, the smaller is the square referred to, and the higher is the precision of the grid reference. For each pair of digits, the precision increases by a factor of ten: SN58 defines a square of (10x10)km^2, 50km to the east and 80km to the north of the origin of myriad SN. SN5881 is a (1x1)km^2 square 58km east and 81km north of that origin. SN 58272 81324 is a (1x1)m^2 area. When stating a grid reference, the precision given should be in line with the accuracy of the position (how well do we actually know where we are?) and with the size of the object (a building doesn't fit on a 1m^2 footprint).

For performance reasons our search engine can only access the first 1000 results of a given search. This is in fact just like Google and other major engines.

If you are trying to view more images, there is a few techniques to use. The best one is to try to narrow your search results. Maybe adding a another keyword. Or even specifing a date range - for example limiting to only recent images.

If you order the results in date submitted (decending or ascending) order, you may be offered a link on the last page to create a new search from that approximate point forward (it does this by adding/changing the date critieria of the search) - in this way you can get though by using a number of seperate searches.

Reusing Geograph Content

RSS, or Really Simple Syndication, allows you to obtain an up-to-date listing of the latest Geograph submissions for integration into another website or RSS reader. For more information, try this Wikipedia article on RSS.http://en.wikipedia.org/wiki/RSS_(protocol)

We have recently added RSS feeds to other parts of the site:
* You will find an RSS button at the bottom of search results, useful to keep updated on local images.
* Registered users can access an RSS feed of the latest topics in the Discussion Forum, and even subscribe to an individual topic, just look for the RSS button!
* the Grid Square Discussions even supports GeoRSS.
* Get an RSS feed of recently updated Articles.
* The newer Content section has an RSS feed.
* Find out about organized meets by following the RSS feed.

(They also accept the format parameter like the main feed.)

If you use the Firefox web browser, you should be able use our feeds as "live bookmarks" - simply click the orange button in the address bar (or in the status bar on older versions).

Photo Contributors

If you are looking for squares to obtain a point, try the coverage maps, and look for green squares; also accessible from that page are various printable checksheets for easy reference in print form. More technical users might enjoy GPX, or Memory Map downloads.

Many of the squares have been captured but only have a few photos; check out the depth map, from which you can find under-represented squares. In the same vein we have a number of maps to show the distribution of photos within a square, usually on a centisquare grid, which divides a grid square into 100 squares, each 100m by 100m.

We have also recently introduced a new map, "Recent Only" this shows recent photos. Help us keep the coverage current by photographing squares without any recent photos (orange or green).

Also look out for Red pin icons around the site, click them to take you to the links page for the location. From that page you can access textual lists of squares in need of photos (as well as direct links to many of the maps on the site).)

Photo Contributors :: Contributing

If you have taken the picture yourself, or you have inherited it from a deceased relative and are certain of the copyright history, the age of the photograph is of no consequence.

With regard to old postcards or photographs without provenance, although the photo may well be out of copyright it is incompatible with the Creative Commons share alike licence and cannot be accepted on Geograph.

If you have taken a current view of the same place and would like to link it to the old photograph you can submit the recent shot here and upload the old photo to Flickr or a similar photo-sharing site and link to it there in your description.

In your description you can create a link to another picture on geograph in 2 ways:
1) By entering the ID surrounded by 2 or 3 square brackets e.g. [[12345]] This will display as a link to (e.g.) " NN2544 : Coire Toaig"

An easy way of getting ID's for your recent photo's is to click on "recent uploads", where the id's are listed in square brackets for you to copy. This can be helpful when creating links before pics are moderated.

You can put links (URL or URI) to web pages and geograph photos into your description, and this will display with the text "link" in the description. Always leave a space after the link to avoid punctuation marks being included in the link. A link to any web resource will work, including a link to a photo on geograph such as http://www.geograph.org.uk/photo/12345. Note that the set of numbers at the end of the url is the photo ID.

You can also link directly to a pic on geograph by entering the ID surrounded by 2 or 3 square brackets e.g. [[12345]] This will display as a link to (e.g.) " NN2544 : Coire Toaig".

An easy way of getting ID's for your recent photo's is to click on "recent uploads", where the id's are listed in square brackets for you to copy. This can be helpful when creating links before pics are moderated.

For more detail, and for editing pics that have already been moderated, we suggest taking a look at Rudi Winter's tutorial (click on "More information on this topic... " below)

Points and Moderation

TPoint or 'Time-gap Point' is a new kind of point. A contributor can gain a TPoint by submitting a contemporary photo to a square that hasn't had a photo for 5 years. The aim is to increase the date range of available photos per square.

I am guessing this is a question as to the suitability of family snaps. The general rule is the people should be the secondary element of the photo rather than the main feature, and posed shots (it can be worked out in most cases) are more suitable to other photo sites as not related to the area they are in. Having said that a discussion thread has refined this recently, and the general conclusion was if there are local events or occupations which are taken spontaneously then a person featuring as the main subject can be included although without a reasonable amount of background would normally be added as a supplemental. But for straightforward posed family snaps then the only circumstance they would be suitable is if they were a small part of the whole scene, and as with most the older the photo the more flexible the criteria.
